OK..but...allegro drivers are higly based on bios calling. there is just few
nativly supported video cards..using vesa is impossible so only way how to
simply port it is to use existing drivers(I really don't want to make drivers
for all existing svga cards...)

I know..but using allekro like key array means that I have to make
independent asynchronous I/O for stdin...this is not easy :(

Yes but when I open dsp and seqenccer it says that dsp/or seqencer is busy...
it is imposible to open both:digital and midi output at time on my gus..
I know with gus I can make digital sound by same way as midi..but other
cards..
(I readed most of linux sources...I know where is problems :)

I have to browse it...
